MCCB for distribution panels — 80 A, 30 kA, 3P
The Schneider Electric G12F3F80 is a GoPact MCCB 125 molded-case circuit breaker, 3-pole, rated 80 A at 40 °C with a TM-D thermal-magnetic trip unit. The 3-pole fixed-mount design with front screw terminals and a toggle control fits standard backplate mounting.
Category A utilisation — no intentional delay for selective coordination. The 80 A TM-D trip provides LI protection: thermal overload (L) and magnetic short-circuit (I).
